Dear Dave
Thank you very much for your answer and for your suggestion. Finally after some google investigation I found some interesting things.

Brian, Thank you very much for your comments. It seems you are happy with 1.6mm timing too. As to the boost pressure, don't you think there is no little room to play with it ? My idea is to increase the boost level to something like 1.05 or 1.1 beyound 5700 RPM . ( with correct AFR of course). I do understand that the K27HFS is able to provide more air volume at high RPM. However it seems the standard K27-7200 still push some air in wastegate at high RPM. ( maybe it's a way to keep turbo's effeciency I don't know) So I am just wondering if there is no little improvment to make.

965 C2T / 1991 3.3 TURBO
